AN APPARATUS FOR MEASURING THE TIME CONSTANT OF A THERMISTOR

摘要

An apparatus for measuring the time constant of a thermistor comprising a first voltage source having the thermistor under test connected to the said first voltage source, a second and third voltage source, each of said second and third voltage sources having a constant output voltage corresponding to elevated and lower limit temperatures respectively a display circuit capable of receiving a start signal (when the output voltage of said first voltage source is equal to that of said second voltage source, said display circuit also being capable of receiving a stop signal when the output voltage from said first voltage source is equal to that of said third voltage source.
